More refactoring of AppProvider to use getTableName() instead of constant.

Browse Source 
Although not used by the temp provider, it seemed strange having some of
the code always using the `DBHelper.TABLE_APP` and other code using
`getTableName()` where all of it could have used `getTableName()`.

Also moved commiting of the temp tables to the real tables into the
`RepoPersiter` instead of in `RepoUpdater`.
